The Penguins of Madagascar Season 2 Episode 40 Rat Fink Episode Title:Rat Fink.Episode Description:After intercepting a rat conversation, the penguins disguise Mort as a sewer rat to go undercover and investigate. There, he finds the rats were just choosing carpets for their sewer. But Mort accidentally blows his cover and gets caught. Skipper and Julien then go down to find him, but end up getting captured as well. They then find out that Mort is being hailed as the rat's new king, the 'Great One', because of the red birthmark on his tail. Mort then plans to lead an invasion on the zoo. After escaping their cell, Skipper and Julien retreat to the surface where they find the rats hugging and kissing the zoo animals. Mort then reveals that his birthmark is really just strawberry jelly he keeps as a snack. The zoo animals then turn on the rats, causing them to retreat back into the sewer. Skipper then congratulates Mort by making him an honorary penguin (like Julien in "Dr. Blowhole's Revenge").
